Well morhz looking at your tutorial there is very little tar at the bottom as you pushed the crapacitors out. These blocks are filled to the top that much heating was required multiple times. I even used a razor blade to slice among the sides. If the rest are like this I may as well disconnect and place them in an old toaster oven on very low heat and perhaps use varsol a mild petroleum solvent used in repair shops to clean engine parts. The heat gun is almost way to hot even on low and isn't kind to the dog bones. It is equiv. to a propane torch as it will burn paint black in a split second. This is all going on with resistors attached going to other circuits etc. Being a British set as they would say somebody went "Willy Nilly" with the tar, enough to tar and feather an individual.
